Hi,
I'm back again! I have been looking at the ogre example code, and I've noticed
that initializes the bones with a specific angle...
Code:
void setupBone(const String& name,const Ogre::Quaternion& q)
{
Ogre::Bone* bone = mBodyEnt->getSkeleton()->getBone(name);
bone->setManuallyControlled(true);
bone->setInheritOrientation(false);
bone->resetOrientation();
bone->setOrientation(q);
bone->setInitialState();
}
void setupAnimations()
{
// this is very important due to the nature of the exported
animations
mBodyEnt->getSkeleton()->setBlendMode(ANIMBLEND_CUMULATIVE);
String animNames[] =
{"IdleBase", "IdleTop", "RunBase", "RunTop", "HandsClosed",
"HandsRelaxed", "DrawSwords",
"SliceVertical", "SliceHorizontal", "Dance", "JumpStart",
"JumpLoop", "JumpEnd"};
//set all to manualy controlled
//Ogre::Bone* handleLeft =
mBodyEnt->getSkeleton()->getBone("Hand.L");
//handleLeft->setManuallyControlled(true);
//Ogre::Matrix3 mat;
Ogre::Quaternion q = Quaternion::IDENTITY;
Quaternion q2,q3;
Vector3 xAxis,yAxis,zAxis;
q.FromAngleAxis(Ogre::Degree(90),Vector3(0,0,-1));
q.ToAxes(xAxis,yAxis,zAxis);
q2.FromAngleAxis(Ogre::Degree(90),xAxis);
setupBone("Humerus.L",q*q2);
q.FromAngleAxis(Ogre::Degree(90),Vector3(0,0,1));
q.ToAxes(xAxis,yAxis,zAxis);
q2.FromAngleAxis(Ogre::Degree(90),xAxis);
setupBone("Humerus.R",q*q2);
q.FromAngleAxis(Ogre::Degree(90),Vector3(0,0,-1));
q2.FromAngleAxis(Ogre::Degree(45),Vector3(0,-1,0));
setupBone("Ulna.L",q*q2);
q.FromAngleAxis(Ogre::Degree(90),Vector3(0,0,1));
setupBone("Ulna.R",q*q2.Inverse());
q.FromAngleAxis(Ogre::Degree(180),Vector3(0,1,0));
setupBone("Chest",q);
setupBone("Stomach",q);
q.FromAngleAxis(Ogre::Degree(180),Vector3(1,0,0));
q2.FromAngleAxis(Ogre::Degree(180),Vector3(0,1,0));
setupBone("Thigh.L",q*q2);
setupBone("Thigh.R",q*q2);
setupBone("Calf.L",q*q2);
setupBone("Calf.R",q*q2);
setupBone("Root",Degree(0),Degree(0),Degree(0));
In principle, I dont understand it... This is done to redirect the bones? If we
orient correctly from a model editor(maya,blender), we wouldnt need to do this,
right? In the model of sinbad for example, the Root bone is oriented with X up.
Doing this, setupBone("Root",Degree(0),Degree(0),Degree(0)); will change
anything?

First I will review the orientation of the bones of my models ... and I will
publish results ...
Thank you!
Cheers,
Aitor
